It turns out that it's hard to get a GRB in this galaxy unless you have a tight binary system, and WR104 is probably not tight enough. The reason is, Wolf-Rayet stars (one of the stars in WR 104, ergo the "WR") lose a lot of mass before they go supernova, and that mass should carry away a lot of angular momentum. That would slow the rotation, and rotation is a very important part of the prevailing "collapsar" model of long-term GRBs. So WR 104 might not threaten us after all, even if we are directly "over" it.
